Make the following expressions free from modulus sign : `(x in R)`
(i) `|x+2|+|x-2|` if `x^(2) le 2` , (ii) `|x^(3)+8|` , (iii) `|x+3|+|x|+|x-1|`

Text Solution

Verified by Experts

The correct Answer is:
(i) 4
(ii) `{{:(-(x^(3)+8)" ""If"" "x lt -2),((x^(3)+8)" ""If"" "x gt -2):}`
(iii) `{{:(-3x-2, x lt -3),(-x+4,-3lexle0),(x+4,0lexlt),(3x+2,xge1):}`
